RESUMO
<p><b>OBJECTIVE</b>To explore the dynamic change and clinical efficacy of acupuncture at Sifeng (EX-UE 10) on appetite regulating factors in the serum of infantile anorexia.</p><p><b>METHODS</b>Eighty cases, in compliance with the diagnostic criteria, aged from 3 to 6 years were randomized into an acupuncture group and a medication group, 40 cases in each one. Additionally, a healthy control group (30 cases) was set up. In the acupuncture group, the pricking method was adopted at Sifeng (EX-UE 10) with the three-edged needle. A few light yellow, transparent viscous liquid or blood was squeezed out after pricking. The treatment was given once a week, for 4 weeks totally. In the medication group, erkangning syrup was administered, 3 times a day, for 4 weeks totally. The ghrelin, leptin and neuropeptide Y (NPY), and the clinical efficacy were observed before and after treatment in each group.</p><p><b>RESULTS</b>The levels of ghrelin and NPY before treatment in acupuncture group and the medication group were lower apparently than those in the healthy control group (all P < 0.01), but the level of leptin was higher appa-rently than that in the healthy control group (P < 0.01). After treatment, the levels of ghrelin and NPY were higher apparently than those before treatment in the acupuncture group (both P < 0.01), and the level of leptin was lower apparently than that before treatment (P < 0.01). All of the above indices in the acupuncture group were improved obviously after treatment as compared with those in the medication group (all P < 0.01). The remarkable and effective rate were 82.5% (33/40) and 32.5% (13/40) and the total effective rate were 95.0% (38/40) and 45.0% (18/40) in the acupuncture group and medication group separately, the results in the acupuncture group were superior to the medication group (both P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture at Sifeng (EX-UE 10) effectively promotes the secretion of ghrelin and NPY and inhibit leptin. It effectively promotes appetite for the children and the efficacy is superior to erkangning syrup.</p>
